SPECIFICATION forming part of Letters Patent No. 635,083, dated October17, 1899..

Application filed May 10. 1899. Serial No. 716,249. (No model.)

To aZZ whom it may concern:

Be it known that we, GEORGE SUMNER and Hours A. WEBBER, citizens of theUnited States, and residents of Braintree, in the is a specification.

. turning the edge over a steel wire 3.

Ourinvention relates to an improvementin presses which are speciallyintended to press meat which has been cooked and form it into cakes orblocks for table use. Our press is adapted also for pressing other kindsof food and articles not intended for food which contain grease or otherliquid matter and which it is desired to press into blocks. It is alsoadapted for extracting juice from fruits and berries.

The invention will now be fully described, and particularly pointedoutin the claims at the end of the specification.

In the drawings, Figure 1 is a side elevation showing the press as itappears when the presser-arms are engaged and the pressure is applied.Fig. 2 is a plan of Fig. 1. Fig. 3 is a side elevation with thepresser-spring arms disengaged from each other. Fig. 4c is a plan of theframe with the springs removed.

The press is best used in combination with a pan of suitable form andconstruction, such as represented by 1 in the drawings, made to flareupward and having a rim 2 formed by An iron or steel base-frame 1 isformed of size and shape. to admit the pan when the presserspring armsare disengaged and thrown back.

. A double presser-spring is pivoted to each end of the base-frame andhas arms which may be brought into engagement with each other to applyand hold the pressure. Each of the presser-springs is bent in themiddle, forminga loop, the loop 5 of one being slightly narrower thanthe loop 6 of the other and being also turned up, so that it may passthrough and lock with loop 6, as shown in Fig. 1. Both springs have arms7, which extend back from the loops, then are wound to form the coils 8,thence have rear extensions 9, terminating in open eyes 10, which hookin cars 11 in the ends of the base frame. A cylindrical bearing-roll 12is inserted through the coils 8 of each spring, being preferably securedto the springs by staples 13 to prevent slipping out. These rolls 12 areof somewhat smaller diameter than the coils 8 when the springs arerelaxed, as in Fig. 3, so as to allow for the contraction when thepressure is applied. The meat 14 or other substance which is to besubjected to the pressure is placed in the pan and a presser-board 15 islaid on top of the meat, while the arms of the springs are unengaged andthrown back, as in Fig. 3. The springs are then tipped over toward eachother to bring the bearing-rolls 12 onto the presser-board, thebase-frame 4: being drawn up against the rim 2, the arms 7 being bent atsuch an angle to the coils that in order to bring them togetherconsiderable pressure will be required, contracting the coils andcausing the rolls 12 to press down upon the board 15. The loop 5 ispassed through the loop 6, and the upturned end 16.0f loop5 will engagewith the loop 6 and lock the two together. The degree of pressure willof course depend upon the tension of the springs.

It is preferable to makethe presser-board 15 of smaller dimensions thanthe interior of the pan, so as to leave an open space around it inorder. that by tipping up the pan the juices or other liquid matter maybe poured off. The bearing-rolls 12 have several advantages. They afforda more even pressure than would be obtained by the coils of the springswithout them and they stiffen and increase the tension of the springs ifmade of such size that the slack is all taken up before the loops lock.

What we claim is '1..A press comprising a base-frame, two

presser-springs pivoted to opposite ends of the baseframe and engagingwith each other when under tension, each spring having tension-coilswhich apply the pressurewhen the springs are locked,substantially asdescribed. 2. A press comprising a base-frame, two doublepresser-springs formed of wires which are bent in the middle and formloops which look with each other to hold the springs in pressure, bothends of the wires being pivoted to the ends of the frame, one springopposite the other, and both branches of each spring havingtension-coils which apply the pressure when the springs are locked, substantially as described.

3. A press comprising a base-frame, two double presser-springs formed ofwires which are bent in the middle and form loops which look with eachother to hold the springs in pressure, the ends of the two wires beingpivoted to opposite ends of the frame, both branches of each wire havingtension-coils, and a bearing-roll for each spring extending through bothcoils, substantially as described.

4. In combination with a pan having an outwardly-projecting rim, a presscomprising a base-frame which surrounds said pan and bears up againstsaid projecting rim, two double presser-springs formed of wires whichare bent in the middle and form loops which look with each other to holdthe springs in pressure, the ends of the wires being pivoted to oppositeends of the frame, both branches of each Wire having tension-coils, anda bearing-roll for each spring which extends through both coils,substantially as described.

5. In combination with a pan havingaprofor each spring which extendsthrough both coils, and a presser-board with which the tension-coilsengage and through which the pressure is imparted when the springs arelocked together, substantially as described.

In testimony whereof we have affixed our signatures in presence of twowitnesses.
